To all ivitom it may confiera."

Be it known that ll, HENRY F. 1VVfiri".iir 12.s,' a citizen of theUnited States, and a resident lot' Chicago, in the county of Cook and State of illinois, have invented' certain new anduseful improvements in Saw-Guards, oit which the tollowing is 'a full, clear, and enact description.A v

The invention relatesto saw guards and more particularly to those adapted for use in connection with metal saws used @for cutting electrotypes andthe like. lin work ot this character, it is essential that the guard be of such a4 character that it will not intertere with the accurate cutting ot the work.

The object 0i1 the invention is to provide V an improved saw guard` adapted for use in connection .with metal saws which permits. the operator to see Ythe cut while it is being made, for accuracy/inl cutting, which will prevent injury to the operator by chips from back-cuttingand which will eiciently protect the' operator.

"lhe invention consists in the several novel features hereinafter set forth and more particularly dened by claims at the conclusion slot therein through which the saw projects, j

is pivotally 'sustained by the support 6, so.- that the saw may receive the necessary attention, all of which may operate and be constructed as well understood in the art. `Usul ally'anadjus'ting screw 8 is'provided between the support 6 and the' table .7;

The improvedl support `for the saw guard comprises a block- Qtvhich is adapted to be4 secured to the underside of the table 7 lby screws 10 and an arm 11 formed of thin or l plate metal and-extended into a ker in the block and securedthereto by rivets12. rlFhe arm 11 is adapted lto extend through the saw slot 7a in the table and extends upwardly and forwardly along the back of the saw and the guard is pivotally connected thereto by `a screw 13. The improved guard comprises body portion 111 which is substantially flat 'Speeication of Letters ratent.

transversely, is disposedover the saw and has no sides, so that the work will be accessible to the operator at the sides of the saw.

`This guard is of considerable width, so :is

to effectively prevent the hands of the operator coming in contact laterally with the upper portion of the saw and its front end isy tapered nearly to a point, as at l5, which is disposed above the tab-le 7 and adjacent the saw.y its a result 0i this formation, the guard will be supported at a sudicient elevationv above the table to permit the work to be pushed bacliwardly against the saw with out visual obstruction to the operator, and this is a very important factor in sawing electrotypes, stereotypes and the like, and, furthermore, the edges of the guard will serve to dedect the ringers -ot the operator laterally away from the saw when they come near the saw teeth. A plate of glass or other suitable transparent material 16 is secured in the top of the guard so that the operator can also see the portions ont the worlr at the bac-lr and sides ofthe saw. it its rear, the guard 14: is provided with ears 1'?, one of which is screw-threaded Eer the thumb screw 13g, so thatv the ears can, it desired, bel

clamped rmly against arm l1 "to iriction ally hold the guard in elevated position.

Plates 18 are secured to the underside oit the g'uard'1d to trap any chips or metal trom .the baclr saw, from beingdedected towardthe operator. ln sawing electrotypes, etc.,

it is desirable to avoid contact between the l guard and the work and by means et clampscrew 13, the guard may be adjusted te avoid this.

rlhe invention exemplifies a' guard in which the cutting pointis always visible to the operator, so that the cutting can be accurately done and this result is attributable to the converging or pointed trout end, the relatively wide i'lat body serving to ede@- tively protect the arms and hands of the operator from contacting with the saw lat-4 erally from the sides thereof.` Furthermore, the tapered edges 15 of the' guard act to delect the fingers; ot the operator as the worlr is being moved backwardly,v it the ngers are brought. near the \sawteeth. The bloclr 10 furnishes a rigid metal support for the arm 11, which Ais limited in thickness, so that it .will pass through the hert in the work, which can be rigidly secured and con; venintly secured to the underside et the table. ,ln mortising a plate, the wide upper lll( rie

portion of the guard prevents chips from the hack of the saw being thrust toward or into the eyes of the operator. to be mortised, it is customary to make'the out with the rear and upper portion ofthe I saw and in doing so, the arm 1l acts as' a guide forthework and the'window lmakes it possible for the. operator to see4 the saw4 and the work.

The invention is not to be understood as restricted to the details 'set forth,v since, these.

may be modified within the scope of the alppended claims, without departing' from t e spirit and scope'of the invention;
